Scientists develop solid-state electrochemical thermal transistor

In modern electronics, a large amount of heat is produced as waste during usage—this is why devices such as laptops and mobile phones become warm during use, and require cooling solutions. In the last decade, the concept of managing this heat using electricity has been tested, leading to the development of electrochemical thermal transistors—devices that can be used to control heat flow with electrical signals.

Currently, liquid-state thermal transistors are in use, but have critical limitations: chiefly, any leakage causes the device to stop working.

A research team at Hokkaido University lead by Professor Hiromichi Ohta at the Research Institute for Electronic science has developed the first solid-state electrochemical thermal transistor. Their invention, described in the journal Advanced Functional Materials, is much more stable than and just as effective as current liquid-state thermal transistors.

Researchers store computer operating system and short movie on DNA

Humanity may soon generate more data than hard drives or magnetic tape can handle, a problem that has scientists turning to nature’s age-old solution for information-storage—DNA.

In a new study in Science, a pair of researchers at Columbia University and the New York Genome Center (NYGC) show that an algorithm designed for streaming video on a cellphone can unlock DNA’s nearly full storage potential by squeezing more information into its four base nucleotides. They demonstrate that this technology is also extremely reliable.

DNA is an ideal storage medium because it’s ultra-compact and can last hundreds of thousands of years if kept in a cool, dry place, as demonstrated by the recent recovery of DNA from the bones of a 430,000-year-old human ancestor found in a cave in Spain.

Tile Adds Undetectable Anti-Theft Mode to Tracking Devices, With $1 Million Fine If Used for Stalking

AirTag competitor Tile today announced a new Anti-Theft Mode for Tile tracking devices, which is designed to make Tile accessories undetectable by the anti-stalking Scan and Secure feature.

Scan and Secure is a security measure that Tile implemented in order to allow iPhone and Android users to scan for and detect nearby Tile devices to keep them from being used for stalking purposes. Unfortunately, Scan and Secure undermines the anti-theft capabilities of the Tile because a stolen device’s Tile can be located and removed, something also possible with similar security features added for AirTags.

Qualcomm takes wraps off world’s first advanced-ready 5G modem-RF chip

On Wednesday, Qualcomm (NASDAQ: QCOM) unveiled the semiconductor industry’s first advanced-ready 5G modem-RF chip that can be used not only in smartphones, but mixed reality headsets, 5G networks and other areas.

Led by CEO Cristiano Amon, Qualcomm (QCOM) said the Snapdragon X75 5G Modem-RF chip utilizes artificial intelligence thats two-and-a-half times faster than previous AI used and better software to bring faster connections to devices, while also allowing them to get better signal strength, data speed and coverage.

Qualcomm (QCOM) added that the chips can also be used in vehicles, an increasing component of the company’s business, as well as PCs, factories and fixed wireless access networks.

Tricorder Tech: Microchip Can Electronically Detect Covid Antibodies In Just A Drop Of Blood

A single drop of blood from a finger prick. A simple electronic chip. And a smartphone readout of test results that could diagnose a Covid-19 infections or others like HIV or Lyme disease.

It sounds a bit like science fiction, like the beginnings of the medical tricorder used by doctors on Star Trek. Yet researchers at Georgia Tech and Emory University have taken the first step to showing it can be done, and they’ve published their results in the journal Small.

Postdoctoral fellow Neda Rafat and Assistant Professor Aniruddh Sarkar created a small chip that harnesses the fundamental chemistry of the gold-standard lab method but uses electrical conductivity instead of optics to detect antibodies and indicate infection.

Sundar Pichai tells Google employees to spend 4 hours with Bard to make it a worthy ChatGPT opponent

Google was referring to its dominant position in the search market. In the early 2000s, several search engines existed in the market, but Google now has 90 per cent of the market. It is also not the pioneer of Android, though it purchased it at an early stage. At that time, the market was dominated by Blackberry and Nokia custom OS (operating systems), but today, Android has the largest mobile OS market share.

In the email, Pichai reportedly remained optimistic and said that AI has “gone through many winters and springs”, adding that the “most important thing we can do right now is to focus on building a great product and developing it responsibly.”

Following Google Bard’s patchy launch last week, Google employees called the rollout rushed and botched. Google was feeling massive pressure from Microsoft, which is leveraging OpenAI’s new-gen ChatGPT technology into its Bing search engine and Edge browser.

AI Is Speeding Us Toward Intelligent Computers and the Singularity, Pioneer Says

ChatGPT and other AI systems are propelling us faster toward the long-term technology dream of artificial general intelligence and the radical transformation called the “singularity,” Silicon Valley chip luminary and former Stanford University professor John Hennessy believes.

Hennessy won computing’s highest prize, the Turing Award, with colleague Dave Patterson for developing the computing architecture that made energy-efficient smartphone chips possible and that now is the foundation for virtually all major processors. He’s also chairman of Google parent company Alphabet.

Theorizing the Basis of Our World: A Reading List on Quantum Reality

Quantum Mechanics is the science behind nuclear energy, smart phones, and particle collisions. Yet, almost a century after its discovery, there is still controversy over what the theory actually means. The problem is that its key element, the quantum-mechanical wave function describing atoms and subatomic particles, isn’t observable. As physics is an experimental science, physicists continue to argue over whether the wave function can be taken as real, or whether it is just a tool to make predictions about what can be measured—typically large, “classical” everyday objects.

The view of the antirealists, advocated by Niels Bohr, Werner Heisenberg, and an overwhelming majority of physicists, has become the orthodox mainstream interpretation. For Bohr especially, reality was like a movie shown without a film or projector creating it: “There is no quantum world,” Bohr reportedly affirmed, suggesting an imaginary border between the realms of microscopic, “unreal” quantum physics and “real,” macroscopic objects—a boundary that has received serious blows by experiments ever since. Albert Einstein was a fierce critic of this airy philosophy, although he didn’t come up with an alternative theory himself.

For many years only a small number of outcasts, including Erwin Schrödinger and Hugh Everett populated the camp of the realists. This renegade view, however, is getting increasingly popular—and of course triggers the question of what this quantum reality really is. This is a question that has occupied me for many years, until I arrived at the conclusion that quantum reality, deep down at the most fundamental level, is an all-encompassing, unified whole: “The One.”

5 Ways ChatGPT Will Change Healthcare Forever, For Better

Over the past decade, I’ve kept a close eye on the emergence of artificial intelligence in healthcare. Throughout, one truth remained constant: Despite all the hype, AI-focused startups and established tech companies alike have failed to move the needle on the nation’s overall health and medical costs.

Finally, after a decade of underperformance in AI-driven medicine, success is approaching faster than physicians and patients currently recognize.

The next version, ChatGPT4, is scheduled for release later this year, as is Google’s rival AI product. And, last week, Microsoft unveiled an AI-powered search engine and web browser in partnership with OpenAI, with other tech-industry competitors slated to join the fray.

It remains to be seen which company will ultimately win the generative-AI arms race. But regardless of who comes out on top, we’ve reached a tipping point.

In the same way the iPhone became an essential part of our lives in what seemed like no time, ChatGPT (or whatever generative AI tool leads the way) will alter medical practice in previously unimaginable ways.

An AI ‘Engineer’ Has Now Designed 100 Chips

Lurking inside your next gadget may be a chip unlike those of the past. People used to do all the complex silicon design work, but for the first time, AI is helping to build new chips for data centers, smartphones, and IoT devices. AI firm Synopsys has announced that its DSO.ai tool has successfully aided in the design of 100 chips, and it expects that upward trend to continue.

Companies like STMicroelectronics and SK Hynix have turned to Synopsys to accelerate semiconductor designs in an increasingly competitive environment. The past few years have seen demand for new chips increase while materials and costs have rocketed upward. Therefore, companies are looking for ways to get more done with less, and that’s what tools like DSO.ai are all about.

The tool can search design spaces, telling its human masters how best to arrange components to optimize power, performance, and area, or PPA as it’s often called. Among those 100 AI-assisted chip designs, companies have seen up to a 25% drop in power requirements and a 3x productivity increase for engineers. SK Hynix says a recent DSO.ai project resulted in a 15% cell area reduction and a 5% die shrink.
